ESP-01S ESP8266 WiFi Module

ESP-01S ESP8266 WiFi Module is a self-contained SOC with an integrated TCP/IP protocol stack that can grant any microcontroller access to your WiFi network. The ESP8266 can either host an application or offloading all WiFi networking functions from another application processor.

Each ESP-01S ESP8266 module comes pre-programmed with an AT command set firmware which means you can hook this up to your Arduino MCU and get WiFi out of the box! The ESP-01S ESP8266 module is a highly cost-effective board with a large, ever-growing community.

The onboard processing and storage capability are powerful enough to integrate it with the sensors and other application-specific devices through its GPIOs and minimal development up-front and loading during runtime.

Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, designed to occupy a minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existence interfaces. It contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.
